* Use `OsRng` in place of `thread_rng`. This changes the defaults of any builder by instantiating an `OsRng` instead of a `thread_rng`, the former being much more secure than the latter. Additionally, all the unit tests that still instantiate RNGs manually used `OsRng`s as well; while there is no actual need for this level of security in tests, the performance overhead is very small and random number generation complexity has such a small impact on these tests that the convenience of being able to ban `thread_rng` from the codebase altogether, setting a good example and avoid issues when refactoring later greatly outweigh the negatives. * Instead of storing random number generators in the various consensus algorithm instances, pass them in from the outside whenever they are needed. This changes a large amount of interfaces (and in this commit is only partially done, since `DistAlgorithm` needs to be fundamentally altered as well. It also obsoletes parts of the `util` module. * Added an `R: Rng` type parameter to both methods of `DistAlgorithm`, forcing callers to pass in their own Rngs. * Fixed documentation grammar and spelling in some of the altered interfaces due to RNG refactoring. * Move `rng` argument to the end of the argument for most functions. Also includes a reformatting due to Rust 1.30. * Updated tests, accomodate `rng`-API changes. * Fixed remaining compilation issues with new RNG code. * Fix illegal `self` import outside curly braces. * Cleaned up comments and fixed broken definition of `broadcast_input`. * Updated existing test cases to properly work with static dispatch randomness. * Do not use boxed `Rng`s for key generation in test networks. * Use the passed-in `Rng` in `ReorderingAdversary`, instead of storing a boxed one. * Fixed clippy lints after refactoring. * Removed some no-longer necessary manual `fmt::Debug` implementations in test framework. * Use `OsRng` even in tests in `binary_agreement_mitm`. * Use a proper deterministic RNG in tests `binary_agreement_mitm`. * Refactor `examples/simulation.rs` by not using `ThreadRng`, passing generic `Rng` parameters throughout and using a type alias instead of a newtype as the `Transaction`. * Remove `thread_rng` use from `examples/node.rs`. * Explicitly construct `InternalContrib` in `DynamicHoneyBadger::propose`. * Fixed typo in description of `DistAlgorithm` trait. |
